邓阜仙钨矿成矿构造特征及深部成矿预测

邓阜仙钨矿位于湘赣地洼系衡山地穹内地洼型花岗岩中。矿床构造为典型的脉状构造。单脉,脉列,脉群在空间上严格按一定的几何关系分布。矿脉雁列脉,侧羽脉的三维形态特征,反映它们剪切形成的机制。经我们对该区航片、卫片分析,发现NNW向构造带与环形影像带,由此而确立了NNW向矿带的新认识。结合矿化与蚀变强度的空间分布,以及发现客观存在的构造等距性、对称性、梯级面,预测出新矿床(体)的空间位置,并得到物探与工程的验证。

METALLOGENIC-TECTONIC CHARACTERISTICS OF DENGFUXIAN TUNGSTEN DEPOSIT AND DEEP METALLOGENIC FORECAST

Dengfuxian Tungsten Deposit Lies in the diwa—type granite in Hengshan Geodome of Xiang—Gan Diwa System. Ore—deposit structures are typical vein ones. At the same time, single vein, vein series and vein group are distributed strictly according to the definite geometric relations. The characteristics of the three dimensional shapes of en echelon veins and flank feather veins show that they formed by shear mechanism, According to the analysis of the aerophotos and satellite—photos of this area, we have discovered the NNW—directed structure zones and circle shadow zones, then established a new opinion of NNW-directed ore—deposit zones. From the space distridution of mineralization and altsrnation intensity, structure equidistance, symmetry and stair face. we have forecasted the location of the new ore—deposit, which was proved by the physical exploration and engineering.
